Cells
What part of the cell controls all activities like
'the brain' of the cell?
The nucleus
What are traits?
Traits things are features or characteristics of a living.
What three main structures are plants classified by?
Root
Stem
Leaves
Define a seed?
A seed is a plant part that can grow into a new plant.
Put these in the correct order of organization from simplest to most complex:
organ system,tissue,cell,organism,organ.
cell-->tissue --> organ --> organ system
-->organism.
Why are plant cells more box-shaped
while animal cells are rounder?
Because plant cells have a rigid cell wall
that gives them shape, while
animal cells only have a flexible cell membrane.
how many kingdoms do scientists use today to classify organism?
6 kingdoms
What do roots do for a plant?
(Name 2 function)
*Roots anchor the plant in the soil.
*Absorb water and nutrients.
What part of a flower makes pollen?
The anther, which is part of the stamen.
Put these classification groups in the correct order from largest to smallest:
Kingdom -->Phylum -->Class -->Order -->Family
-->Genus -->Species.
Which part of the cell is the outer covering that lets things in and out?
The cell membrane
Which two kingdoms include only single-celled organisms?
Archaea and bacteria.
What part of a leaf allows carbondioxide to enter and water to escape?
Stomata
Define pollination?
Pollination is when pollen moves from the anther of a flower to the pistil.
Define respiration in plants?
The process where sugars made during photosynthesis and breakdown to release energy using oxygen and giving off carbondioxide and water.
Viruses are smaller than cells. Why are they not considered living things?
Because they cannot make food
or
they cannot reproduce on their own or use energy.
They need a host cell.
Mushrooms belong to which kingdom, and why are they not plants?
Fungi-because they do not make their own food.
How are mosses and ferns different from plants like flowers and trees?
Mosses and ferns reproduce with spores instead of seeds.
How are seeds in conifers different from seeds in
flowering plant?
Conifer seeds grow on the surface of cones, while flowering plant seeds grow inside fruits.
If a plant does not make seeds, how could it still make new plant? Give two examples?
Some plants grow new plants from runner, from pieces or bulbs/tubers.
Runner-- strawberries
cutting--roses,hibiscus
Bulb/tubers--onion bulb or potatoes
Which organelle acts like a 'storage room' and how is it different in plant and animal cells?
Vacuole - In plant cells it is large to store water and support the cell's shape.
In animal cells it is small.
What are the two parts of the organism's scientific name?
The first part is the genus,
the second part is the species.
Define stomata?
Tiny holes on the underside of leaves that let carbondioxide in and water and oxygen out.
How does nectar help both the plant and the pollinator?
The pollinator gets food and the plant's pollen is carried to another flower.
Imagine a flower produces pollen but all the bees and insects disappear.What could happen to that plant's ability to make seeds?
Without pollinator's, the pollen may not reach the pistil, so fertilization won't happen.The plant would not make seeds or fruits unless pollinated by wind or another method.
